3.3.12 If the Ultra Vac is being installed on a Lazer Z with a serial number less than
260,000, it is recommended to replace the steel blocker plate mounted across the
bottom of the blower with the reinforcement plate (Item 48) and small blocker
plate (Item 26) included in the completing kit. Use the hardware that was
removed when removing the large blocker plate (See figure 8). Failure to install
a blocker plate will create a thrown object hazard that could injure or kill
bystanders, or cause property damage. This modification should not be done
if the Ultra Vac blower will be mounted on a Lazer Z with a serial number of
260,000 or higher.

units with serial numbers less than 220,000. Measure and mark the deck
stiffener (See figure 9). Trim off the indicated portion of the stiffener. Touch up
the trimmed area with Exmark red touchup paint – P/N 1-850337.

3.3.14 Using the knob that was removed with the original belt cover stud and the knob
included with the completing kit (Item 40), mount the two belt cover supports (Item
39) to the plastic belt cover (Item 10). Position the belt cover on the mower deck.
The lower ends of the belt cover supports should rest on the outside of the deck
stiffeners. Mark the location of the belt cover support holes on the deck stiffeners.
Remove the belt cover. Center punch and drill 3/8” holes.
